一种新型混凝土管梁柱节点受力性能分析

摘要

A new type of joint for concrete tube column and beam-beam bar cross-core type joint is proposed. Concrete tube beam-column joint model and common concrete beam-column joint contrast model is established by FEM software ABAQUS, to conduct the vertical loading, the horizontal loading unidirectional and horizontal low cyclic loading. The test show that the vertical resistance capability of tube column joint is higher than that of common joint by 17. 5% , horizontal bearing capacity are not significant different and the plumpness of displacemrnt-column end load hysteresis under low reversed cyclic loading is slightly poor.%提出了一种新型混凝土管梁柱节点——梁筋穿心式节点,借助ABAQUS软件,建立了混凝土管梁柱节点模型以及普通混凝土梁柱节点对比模型,进行竖向加载、单向水平加载和水平低周反复加载.研究得出管柱节点比普通节点竖向承载力高17.5％,水平承载力相差不多,低周反复加载下的位移-柱端荷载滞回曲线饱满度略差.
